Geothermal pumped well projects provide power to the grid at a contract price and terms negotiated with the power off-taker. This can vary significantly from country to country, but as…

Extended reach drilling for geothermal energy production

Henk Kombrink

October 3, 2023

The energy transition is about pipe, lots of pipe. Where gas can be transported across the globe, geothermal energy, especially the low-temperature version of it that is mainly used for…

A geothermal gold rush

When it comes to producing geothermal energy, Munich is without a doubt the place to be in Germany. As the map here clearly shows, the city is dotted by wells…

Groundwater flow – a potential cost-saver for shallow geothermal loops

Henk Kombrink

July 26, 2023

The energy transition is all about pipes. Where a single gas well was sufficient to deliver energy to power an entire city until recently, closed-loop geothermal boreholes are now increasingly…

Understanding geothermal energy
